I think the problem here is that we're not trading for the present...instead, we seem to be looking at the past resumes of the vets (Nocioni averaged 23 and 10 in the '05-'06 playoffs, Gooden has been to the NBA Finals as a starter with the Cavs) because their current seasons seem to be nondescript. Both have already peaked, and are best fit for playoff teams, and not for us.
Not only that, the youth we are trading for have been tested and tried by many other teams (Diogu's 3rd team with us, and Simmons's 4th) and at some point their potential has to be exhausted, despite their age--they are what I call "end of the bench potential players"--players who can't get minutes and rely on their "potential" and cheap contracts to stick in the league. I like Diogu so maybe I shouldn't be too harsh, but when we were unable to trade for "productive potential" in Nate Robinson, Tyrus Thomas or Joakim Noah, therein lies the problem.
I wish Geoff aggressively swung a move for real talent who can be with us for the long term, rather than assembling a group of busts, has-beens, undersized big men and average veterans. It might be interesting to see if there's any diamond in the rough players (that's what we thought we had with Beno at least...) but it's not a conducive way of assembling a playoff team. I know we're trying to clear salary for the long run, but it's best to assemble talent along the way instead of what seems to be on the losing end of trades time after time.
